Abstract. The study analyzed the technical efficiency among cowpea farmers in Mubi South Local Government Area of Adamawa State, Nigeria. Data were collected from 100 respondents randomly selected cowpea farmers using multi-stage, purposive and simple random sampling process. The result of the stochastic frontier production function shows that sigma squared was 0.656 and significant at 1% level, indicating good fit and correctness of the distributional form assumed for the composite error term. The value of gamma was 0.522 and significant at 1% level, suggesting that 52% of the variability in the output of farmers was due to differences in their technical efficiency. The coefficients of farm size, seed, fertilizer, agro-chemicals and labor were positive and significant at varying levels indicating direct relationship with output of cowpea production. The analysis of the inefficiency variables revealed that education, farming experience and extension contact decreases technical inefficiency of the farmers. Mean technical efficiency (TE) was 0.78 with the minimum and maximum values of efficiency as 0.53 and 0.97, indicating that farmers have the potential to increase their TE by 21.2% in the short run given the current state of technology. To achieve this, policies by the government and nongovernmental agencies should be geared towards encouraging farmers’ education on farm management practices so that they would be able to allocate production resources more efficiently especially fertilizer and herbicide for optimum yield.
